ns87415_check_atapi_dma(9)

🌸 NAME 🌸

okay bestie, welcome to ns87415_check_atapi_dma(9) from the Kernel API Manual — it's literally the ATAPI DMA filter 💅

✨ SYNOPSIS ✨

int ns87415_check_atapi_dma (struct ata_queued_cmd *qc );

🎀 ARGUMENTS 🎀

• qc — the Command block, bestie. that's the whole argument vibe 🫶

🦋 DESCRIPTION 🦋

so the move here is: Disable ATAPI DMA (for now) ✨

and yes, maybe we could do DMA if we kill the prefetching — but this isn't clear 🙈 no cap, that's the whole situation. lowkey mysterious, highkey the actual description.

for now = ATAPI DMA is disabled. The prefetching idea is not settled, fr fr.
